Definition and dynamic control of a continuous chromatography process independent of cell culture titer and impurities.

Advances in cell culture technology have enabled the production of antibody titers upwards of 30g/L. These highly productive cell culture systems can potentially lead to productivity bottlenecks in downstream purification due to lower column loadings, especially in the primary capture chromatography step. Alternative chromatography solutions to help remedy this bottleneck include the utilization of continuous processing systems such as periodic counter-current chromatography (PCC).

Passive multivariable temperature and conductivity RFID sensors for single-use biopharmaceutical manufacturing components.

Single-use biopharmaceutical manufacturing requires monitoring of critical manufacturing parameters. We have developed an approach for passive radio-frequency identification (RFID)-based sensing that converts ubiquitous passive 13.56 MHz RFID tags into inductively coupled sensors.
